Rare Mech Missing From Market?

So I just started playing, and after a few missions I get a message that a "rare mech is available nearby"...

So I look and its just a couple systems away so I go jump over to see.

Its a Blackjack... selling for just over 3 million.

Well, I didn't even have 1 million at that point so I went back to do more missions and build up my bank roll, and all the while the Starmap continues to list that "Rare Mech BlackJack available!" over the system where I found it... its even popping up on my "home screen" under "system data" that there is a Black Jack available to purchase there.

So I keep playing for a couple days, build up more bank roll and finally after saving up 4 million, I decide to go back and buy the BlackJack.

Only problem being that the BlackJack is no where to be found now!

Yet, it keeps telling me that "rare mech blackjack available!" in that system.

So whats the deal, if its not there anymore, why does the game keep telling me its still there?

Its even popping up on the "console" screen you access through the bridge of your ship above the mech bays.. where that blonde chic is always standing, telling you what to do. Its there on that console screen like a mission would appear, as though I'm "supposed" to go buy that particular Mech...

Every time I open the star map its there too...

So how do I get rid of all these if the mech isn't actually going to be available?

I mean I actually wanted this particular mech, as it was a Blackjack, the same one you started out with in PG's MechWarrior game... and I kinda wanted it for the whole nostalgia thing... but if its not going to be there then I don't want the game to keep telling me "Hey! HEY! Its here! ITS HERE!" .. you know...
